Hide in the cigarette mechanism controls dish 90, accept temporarily to remain in the store loop 93 by the pyrotechnics calamity detector 91 detected signals that are arranged on the building side by the device 92 of transmitting messages.In addition, utilization as the part in the door open and close controlling loop 94 of the part of elevator operating control device promptly, door closes and detects loop (with the mechanical locking mechanism interlock) 95 opposite houses and be closed and confirmed, when make door close detection signal and pyrotechnics calamity detection signal is consistent by AND condition loop 96 after, make screening cigarette action motor-driven by hiding cigarette driving ring current 97, drive flexible screening smoked sheet by hiding the cigarette action link rod, to hide cigarette.Such as, detect the floor of transmitting messages and be in door when opening the state that carries out on-board and off-board when cage arrives the pyrotechnics calamity, if screening cigarette mechanism is moved, then can have problems by following reason, thereby after regular or normal operation and on-board and off-board finished, landing door was in that to hide the cigarette action under the closing state more just suitable.
It is the reasons are as follows: have before landing door arrives the door off position, door closing device is not applied the such advantage of load.When landing door is opened, also be fully nonsensical even allow smoke shielding device move.In addition, landing door is opened, make earlier to hide the cigarette mechanism action, carry out the door shutoff operation of landing door then, then can avoid door portion in the rising wood of landing door and lower edge to produce and hide dragging sliding obstacle, make the door closing movement of landing door stay puckery and causing the danger of not exclusively closing between the smoked sheet.
Adopt the present invention, from the door open position of landing door to the zone that door is about to close till, have flexual screening smoked sheet 41,51,61 and only leave the gap, thereby slip sound, wear track etc. can not take place with respect to tripartite architrave face.
Only door be about to Close All near (about about 10mm) need be to hiding the thrust pressure of smoked sheet.
To hide the cigarette mechanism action in order making, the horizontal direction of door hanger to be moved as propulsion source, do not need independently to drive propulsion source mechanism, simple in structure, also have very big advantage aspect manufacturing cost, the maintenance cost.
Even the door at ordinary times door also can guarantee to hide hood during closing movement.
Therefore, do not need the signal of cigarette detection of fires detector, the signal of transmitting messages to send receiver, distribution etc. yet, have very big advantage aspect manufacturing cost, cost of installation, the maintenance cost yet.
Improve as long as the part that door hanger portion, flexible are hidden smoked sheet etc. carries out supplementary sum, also can add the screening hood the elevator of Dd.
Thus, can realize the screening cigarette between the minim gap of the elevator landing door compact, simple in structure, that reliability and stability are high, that can restrain the building fire as far as possible prolongs burning speed, the disaster that reduces that cigarette causes that personnel sacrifice etc.
